But I think it’s used when you want to connect a vCloud Air network (which is part of a Disaster Recovery or Virtual Private Cloud setup) with the network of a vCloud Air PaaS such as vCloud Air SQL. I base this on this vCloud Air SQL Users Guide that talks as about enabling the service network to connect a vDC (vCloud Air Virtual Datacenter) to the vCloud Air SQL network.

Trying out vCloud Air at work and I wanted to install the vCloud Air plugin for vSphere web-client. The installation kept failing though. Initially it was due to the vCenter server not having access to the Internet (not your browser, the vSphere web-client itself needs to have access) but even after I specified a proxy (check out this post on how to specify a proxy) and gave vSphere web-client access to the Internet the download would begin and fail.
